Delete individual files from the media app, or navigate to the pictures folder and delete that way.

No way to delete multiple files using the handset. Use mass storage mode and a computer to move/copy/delete a number of files at a time.

EDIT: Corrections (thanks rambo)...In the media app, click select from the menu, then hold the caps key and scroll to highlight and select multiple pictures. At least this works on my 9900. I didn't realize this was possible. I assume you can then delete all selected. Posted via BlackBerryForums.com Mobile
